Hearing Conservation Manual 17 Appendix III - Training Information Training Information Hearing Conservation Program A. Reasons for wearing a hearing protection device (HPD) 1. Compliance with standards – various locations and job assignments have been designated as “noise hazard” areas. 2. Noise exposure in the work area may damage hearing over a given time. 3. People with a known hearing loss may accentuate the loss rate if hearing protection is not worn. 4. Many employees notice a reduction of anxiety and fatigue at the end of the work day. B. Ensure earplugs and/or muffs fit properly 1. Different types are available. 2. Comfort and effectiveness are important (but if the ear plugs or muffs are not effective, comfort means nothing). 3. Your voice will sound “muffled” or “hollow” (similar to how voice sounds when talking into a hollow tube). 4. Insertion technique a. Allow time for rolled foam plugs to expand after insertion. See instructions on package. b. The muff cushion should fit comfortably (make sure it is always flexible and forms a good seal around the ear). C. Proper cleaning and care of the hearing protection device (HPD). 1. Expandable foam: dispose of when dirty. 2. Preformed: wash with warm water and mild soap. 3. Muffs: clean cushions with damp cloth rinsed in mild soapy water. 4. Do not tamper with plugs or muffs – drilling or poking holes in them destroys their effectiveness. D. Who to contact when you have problems or need replacements. 1. Immediate supervisor. 2. Central Stores (replacement hearing protection devices). 3. Occupational Medicine (hearing problems or discomfort/persistent ear pain, drainage, dizziness, or ringing in the ears). 4. EH&S (changes in procedure, equipment or other noise related problems). E. Failure to wear HPDs as required. 1. Disciplinary action will be taken as required (flagrant and purposeful violation may lead to termination).
